Abstract: Objective To diagnose highly suspected brucellosis spondylitis (BS) by dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) and computer tomography (CT), and to analyze the diagnostic value of the combination of DCE-MRI and CT in BS. 
Methods A total of 80 patients with highly suspected BS admitted to the First Affiliated Hospital of Hebei North University were selected as the research subjects. All patients underwent pathological examination, CT and DCE-MRI. Taking pathological examination as the gold standard, the diagnostic value of DCE-MRI combined with CT for BS was analyzed. 
Results Among 80 patients with highly suspected BS, 58 cases diagnosed with BS by pathology were selected as BS group, and the remaining 22 patients were selected as non-BS group. Ktrans, Kep and Ve in BS group were higher than those in non-BS group (P＜0.05). The sensitivity and accuracy of DCE-MRI combined with CT in diagnosing BS were higher than those of DCE-MRI and CT alone (P＜0.05). The specificity of CE-MRI combined with CT in diagnosing BS was not statistically significant compared with DCE-MRI and CT alone (P＞0.05). 
Conclusion Both DCE-MRI and CT can be used to effectively diagnose BS, which can effectively display the pathological characteristics of BS. However, the combination of DCE-MRI and CT is more effective for BS.
